Question

\(\frac{6}{7}:\left(\frac{3}{26}-\frac{3}{13}\right)+\frac{6}{7}:\left(\frac{1}{10}-\frac{8}{5}\right)\)

Answer 1

\(=\frac{6}{7}:\frac{-2}{26}+\frac{6}{7}:\frac{-3}{2}=\frac{-78}{7}+\frac{-4}{7}=\frac{-82}{7}\)

Answer 2

=\(\frac{6}{7}:\left(\frac{3}{26}_{ }-\frac{6}{26}\right)+\frac{6}{7}:\left(\frac{1}{10}-\frac{16}{10}\right)\)

=\(\frac{6}{7}:\frac{-3}{26}+\frac{6}{7}:\frac{-3}{10}\)

=\(\frac{6}{7}.\frac{-26}{3}+\frac{6}{7}.\frac{-10}{3}\)

=\(\frac{6}{7}.\left(\frac{-26}{3}+\frac{-10}{3}\right)\)

=\(\frac{6}{7}.\left(-12\right)\)

=\(\frac{-72}{7}=-10\frac{2}{7}\)

Answer 3

\(=\frac{-52}{7}+\frac{-4}{7}=-8\)
